The roof to a Waitrose distribution centre has been completely refurbished in a single ply membrane system chosen for its sustainable credentials and no disruption to the retailer’s 24/7 operations at Aylesford near Maidstone, Kent.

Our Roof Hatches have been installed on top of many buildings around the world. For this project, our Roof Hatches were installed with stunning views of Alexandra Palace.To suit the building's style, these hatches feature an anthracite powder coat finish, not only enhancing their durability but also adding a contemporary and stylish touch to the overall aesthetics.Thanks to the gas struts, opening and closing these hatches is effortless, ensuring convenience and ease of use.

This project in Derbyshire involved treating cut edge corrosion, re-coating the roof and lining the gutters. Products used were * Metalaseal BBA Approved metal roof coating system * SWT Primer (to treat rust in the gutters and cut edges) * Liquasil One and Non-Sag Sealer to line the gutters. The project is covered by the unique Liquasil Latent Defects Guarantee, which is written specifically for Liquasil and underwritten by an A-Rated, Lloyds of London insurer.

When specifying the most appropriate method of waterproofing for a new-build basement it is advisable to follow the recommendations within BS 8102:2009 ‘Code of Practice for Protection of Below Ground Structures Against Water from the Ground’. The standard advises on the types of waterproofing available and confirms the performance grade to be achieved. This project required Grade 3 protection – no dampness or water penetration acceptable.

SIG Design & Technology and SIG Insulation are working with the Interserve Kajima consortium on a batch of seven secondary school projects to deliver a value-engineered, robust roofing solution. At Stopsley High School there are two roofs installed by Briggs Amasco in an approximate 16 week programme. The largest roof measures some 2500m2 and the inverted roof build up selected and supplied by SIG comprises IKO’s PermaTEC hot melt waterproofing system.

A project utilising our Del Carmen Spanish Slate took home the award for Roof Slating at this year’s UK Roofing Awards, hosted by the National Federation of Roofing Contractors (NFRC).

FDT harnessed the most modern roofing materials and advanced 21st century technological know-how to help preserve one of Europe’s most remarkable ancient monuments, 5,000-year-old Skara Brae. The designated World Heritage Site, a fascinating commune of small interlinked stone dwellings, is one of the most-visited tourist attractions on the historic Orkney islands and offers up to 60,000 visitors a year an unparalleled taste of life in Neolithic Orkney.

This project, to coat approximately 2000 sq metres of asbestos roof with the BBA Approved Asbestsoeal system is a lesson for all in correct health and safety. Liquasil provides all approved installers with H&S training as standard. This deals with correct use of netting, scaffold, walkways, work platforms and waste water filtration from asbestos roof cleaning. Having already completed 500sq metres on a unit a year previously, the contractor was invited back to complete the rest of the block, which is the best possible endorsement.

The Little Chapel in Guernsey was built in 1914 and, at only 16 feet by 9 feet, is said to be “one of the smallest functioning chapels in Europe, if not the world”. The chapel and its unique appeal gained national fame after an article accompanied with a colour photograph was published in the Daily Mirror, and it has since been considered one of, if not the most famous tourist attraction in Guernsey.In 2015, work began to weatherproof the intricate building, with the Protec System specified as the best solution for the job.The ChallengeHaving never been finished by its original builder, Brother Déodat, the chapel has been undergoing a long-term restoration project to create a structurally sound building that retains the beauty of the original vision. Firstly, the foundations were underpinned and properly secured for the first time since they were created over 100 years ago. The next priority was to fix the roof, as described by Pat Johnson, chairman of the Little Chapel Foundation:“The asphalt on the roof was hollow and had to be taken off. The concrete underneath was hollow. We ended up with a substrate of soil and clink, so to repair it we had to go inside and grout all the cracks in the ceiling. [The new roof] comprises three layers of concrete, 340 stainless-steel plugs, a stainless-steel mesh and a final coating of concrete”.The task of making the new concrete surface waterproof fell to local Polyroof approved contractor Sarnian Roofing Ltd. Andy Gavey (Company Director) said about the project:“As a boy I would regularly visit The Little Chapel and I’ve always been blown away by its beauty and character. To get the chance to help restore the building to its full potential is a dream come true for me – this has to be my favourite roofing project yet. Polyroof’s contribution towards the roofing works has meant that we were able to provide a top-quality roofing solution that has done justice to the amazing exterior of the building.”The SolutionWith its ability to be applied directly to the concrete to form a lightweight, seamless and durable waterproofing membrane, Polyroof’s Protec System was a clear choice for waterproofing the chapel roof.The first stage was to make the entire roof area fully watertight. Following a coating of primer to seal the porous concrete surface, the first coat of Protec was applied which incorporated fibreglass reinforcement. After 30 minutes the coating had cured and the second coat was applied to the whole roof area. To areas where new mortar was laid to re-embed the pebbles and seashells, which had been painstakingly removed from the old roof, a coating of Polyfinish was applied to provide extra protection.The architect chose a sanded decorative finish to complement the exterior of the building, which is covered in a mosaic made from seashells, pebbles and broken china. To create this finish, a third coat of Protec was applied and, whilst still wet, Quartz Sand was broadcast into the resin. After brushing off the excess sand, the whole roof surface was sealed with an application of Polyfinish Clear.

A sense of community, abundant greenery and lake views on the roof terrace for all residentsThe housing fair is held annually in Finland. In 2021, it will be held in a scenic location in Lohja, Southern Finland. An interesting partnership quarter will also be put up in the fair area, where a sense of community has especially been taken into account in the planning. A block of 34 modern and energy-efficient apartments. The principal designer of the site is the architect Sasu Alasentie from UKI Arkkitehdit.”The idea behind the whole quarter is a sense of community. The flats in the building do not have their own saunas, but instead a communal use sauna will be constructed on the roof terrace. You can see the wonderful lake scenery from the roof and by utilising the roof terrace we wanted to ensure views of the lake to all residents. The yard areas of the quarter are fairly compact, but the roof terrace creates more greenery and communal outside areas for all the residents to use. We also hope that this will increase the residents’ team spirit and sense of community,” says Sasu Alasentie about the basis of the planning. ”On the roof terrace, we will also build an individual planting box for each resident, where they can cultivate herbs, flowers or whatever plants they want. A small summer kitchen corner and dining area will also be built there, as well as hanging chairs for lounging around. All in all, the area will hopefully become a communal, green oasis to spend time in, for all the residents,” says Sasu Alasentie. ”When we were choosing materials for the terrace, it was important to us that they would be in keeping with the building’s ecological nature and energy efficiency. Together with the contractor, we decided on the UPM ProFi Piazza composite for the terrace material. What appealed to us about it was particularly its durability and that it was easy to look after. Naturally also the fact that it’s made of recycled material, which fits well with the environmentally-friendly ideology of the whole building. I believe that in future projects, environmental friendliness and materials made from recycled materials will become even more popular,” says Sasu Alasentie.  

A detailed visual and physical inspection, together with core and moisture probe analysis carried out by IKO on the roof, patio and walkway areas, indicated that the waterproofing membrane was in a condition commensurate with the age and the type of the traditional membranes installed. They had become fragile and brittle. The decks were saturated due to water ingress, and natural ageing had played a principle part in the deterioration of the waterproofing system. The build-up would not have met the requirements of the current building regulations Part L. IKO worked to refine the specification for the main roof,

Hundreds of homes have been refurbished as part of a multi-million pound revamp of housing association properties.Tristar Homes spent £8m on the scheme at Kennedy Gardens in Billingham where they carried out work on 225 properties across the three housing blocks as well as creating 12 new one and two bedroom homes which have been made available for rent.The development, completed in September 2014, includes the fitting of new windows, new bathrooms and improved living space due to the new balcony extensions.The roof area before its refurbishment had a U-value of 0.4 W/m²K. This existing build-up would not have met the requirements of the current building regulations Part L.The lower roof had been overlaid at least twice since its original construction. In all but one core sample, the existing insulation was wet through and therefore it was apparent that 90% of the existing roof build up needed stripping to the original asphalt. A further inspection was needed when the asphalt was exposed to ascertain the condition and depth of the asphalt. The asphalt was deemed in reasonable condition so the new system could be installed onto the original asphalt.IKO worked with installing contractors BriggsAmasco to refine the roof specification and recommended IKO Mach One single layer bituminous membrane system, installed to the recommendations of wind uplift calculations and performing to a 0.18U value as per requirements.IKO Mach One membranes are a robust, flame-free, single-layer roofing system with added fire-retardancy. IKO Mach One can be mechanically fastened, ballasted or bonded with polyurethane adhesive.A 20-year insurance-backedfire retardancy guarantee was issued to cover all materials, design and workmanship covering contractor insolvency.

The client contacted us in urgent need of a green roof solution before a project handover. Green roof was part of the planning application. Pre-grown panels with patented design were delivered on pallets and lifted to the roof via forklift. The ingenious connecting system means each module clicks to its neighbour tightly and securely so once installed, the sedum has a seamless appearance. The plants are a mixture of sedum species ideal for the UK climate. They are well rooted into Wallbarn's bespoke substrate and fully mature. 250 sqm of green roof was installed in 1 day.

The asbestos cement roof to this industrial unit in Hereford was heavily contaminated with moss and lichen and was leaking in numerous places. The moss and other vegetation was first dampened down, scraped off and placed into designated asbestos waste bags for licensed disposal. The roof was then steam cleaned. All metal fixings were treated with Liquasil's rust primer and sealed with Non-Sag Sealer. Small holes and cracks were sealed with Non-Sag Sealer. The entire roof was then coated with Asbestsoeal 20 and is now resistant to moss growth and water leaks.

Glazing Vision have worked on a number of projects with Architects, ARCHEA, who are Victorian house experts specialising in adapting period houses into modern homes. These homes regularly demand an uplift in natural daylight, and Glazing Vision have formed a great relationship with ARCHEA to help transform many of their projects into well-lit, healthy, and happy environments for a number of families.These particular homes are all located within 10 minutes of each other in Hackney, London, with all clients looking to transform their period property into a contemporary home. Each project involved an extension and required a significant increase in natural daylight to help better the health and wellbeing of the families residing in each home which is where Glazing Vision stepped in.“When adding a ground floor extension, we often need to include rooflights to add light and views both to the new spaces and existing rooms in the home. Whilst fully glazed roofs can be used, this approach typically incurs more cost and extended lead-times due to the glazing being bespoke and needing to be made to order. By using large format, off-the-shelf rooflights we can incorporate extensive areas of glazing, but at a much lower cost and faster turnaround. We then use these in combination with traditional roof construction techniques, which are simple to construct and maintain.” – Richard Skinner, ARCHEA.ARCHEA regularly specify Glazing Vision’s Flushglaze Fixed Rooflight, a minimalist product with ‘frameless’ internal views designed to allow as much natural daylight into a room as possible. When working with pitched roofs, ARCHEA often opt for the Glazing Vision Pitchglaze Fixed Roof Window which is designed to be installed in pitched tiled roof applications flush with the tiling line, providing you with a vast amount of natural daylight.“We initially chose Glazing Vision because of their wide range of high-quality rooflights, and since working with them on a number of projects we value the help of their Technical Sales Team who are always on hand for technical support. We typically use the Flushglaze Fixed units as the extensions we work with usually involve a flat roof for practical and planning reasons and the Flushglaze offers the largest and best value standard glazing solution on the market. The standard aspect is vital for us as we are often looking for short lead times, and so this element adds so much value. When working with pitched roofs we instead use the Pitchglaze Fixed Roof Window which fit flush within the roof offering a sleek finish.” – Richard Skinner, ARCHEA.You can purchase our off the shelf rooflights and roof windows via rooflights.com, our online rooflight shop!Photography: Mai-ling Leung of ARCHEA

Features in 2015 on Grand Designs was an enormous modern house inspired by Ludwig Mies van der Rohe’s German Pavilion in Barcelona. This house adds to this oeuvre on a massive scale, reflecting the footprint in two connected pavilion buildings spanning 60 metres, with a swimming pool in place of the reflective pool. With single storey modernist buildings of this type the largest surface is the one that is not seen – the flat roof. In the case of Pavello the roof is a full 600m2 of Armourplan P with a bespoke fabricated edge detail.

The Koster TPO Single Ply membrane was selected to waterproof the flat roof on this new build development. The design called for a warm roof system installed over a timber deck followed by a sedum blanket (on protection membrane).Koster TPO 2mm Fleeceback membrane was used as it is highly resistant against mechanical damage, fully weldable so no weaknesses and it will not contaminate any of the planting such as a PVC membrane would.The Slate Grey RAL 7015 colour was selected to compliment the Zinc cladding.

11 Freebournes RoadBauder reinforced bituminous waterproofing system with BauderSOLAR FSynopsisA large derelict warehouse located in Witham has undergone major renovation to transform it into a storage centre for Essex County Council that will assist its services and benefit the local community. The refurbishment works were designed and project managed by Lambert Smith Hampton on behalf of the client, who wanted the building to act as a benchmark for sustainability with the roof playing an integral part in achieving this through the addition of solar panels.Bauder Building BoardProject Name:11 Freebournes RoadLocation:Witham, EssexRoof Size:5,200m²Client:Essex County CouncilProject Manager:Lambert Smith HamptonApproved Contractor:Acclaim ContractsPV Installer:CJ SolarEnvironmental focus:Solar PVThe specificationWorking closely with the client, Bauder performed a comprehensive roof evaluation survey to identify the full extent of water ingress being experienced and to confirm the suitability of adding solar. The bespoke survey report highlighted that the roof needed to be stripped back to its original deck, before being waterproofed with over 5,200m2 of Bauder’s reinforced bitumen system by Acclaim Contracts. 588 solar PV modules were then fitted onto the roof by electrical installer CJ Solar, enabling the client to generate at least 134.70 Megawatt Hours of solar power each year. Products appliedBauderSOLAR FIntegrated photovoltaic system, where the modules and the substructure are combined to form a single unit, which is secured to the roof without any penetration of the waterproofing or roof deck. System installedReinforced Bitumen Membrane System1 Reinforced bitumen membraneTorch applied, elastomeric bitumen capping sheet2 BauderPIR M 60Rigid urethane foam insulation faced on both sides with aluminium foil.3 BauderPIR FA-TETorch applied air and vapour control layerAdvocacyJulian Sanchez, Commissioning Delivery Manager for Essex County Council: “We actively look for opportunities to implement renewable energy and knew that this storage facility lent itself well to PV retrofit.

Located in Anglesey and operated by Bangor University, Menai Science Park is the flagship building for Wales' first dedicated science park. The facility is built to BREEAM Excellent standards and comprises of 5,000 sqm of offices, laboratories and workshop space for up to 700 people - from start-up businesses to large corporate companies. The building's structure features a striking white continuous flowing ribbon that forms wall, floor and roof surfaces and wraps around the glazed facade to the front elevation. The two-storey entrance connects to the main three-storey, traditional brick cavity U-shape building,m which houses the laboratories and offices and features a facade that encloses an open courtyard. Aluminium curtain walling from Technal was installed and spans 74m x 11m. This had to follow the curvature and flow of the ribbon at the point of fabrication. The key area for this facade is the first floor horizontal and sloping ribbon - the curtain walling continues behind the Corian rainscreen. One particularly challenging detail is the 6m glazed linking walkway that connects the innovation area to the brick-built main building. Designed with a double-pitched roof, the curtain walling follows the long contours across the two pitches of the roof at an angle. This involved calculations and modelling to accommodate the difficult compound angles to ensure the desired architectural intent was achieved. Throughout the building, aluminium casement windows have been installed, some as inserts within the facade including automatic opening vents, and to the courtyard elevations. Completing this contemporary outdoor space, the windows are complemented with timber rainscreen panels.

New Era cradles were used to lay a level decking system on a roof terrace that had natural sloped drainage. We used UC4 treated external swedish softwood battens and composite decking to ensure long lasting and maintenance free-use.
